We use TFormSize a alot, as it's simple to use and does what we want.
However, we would like to get an extra property on the component.
Some of our users have our program installed on a readonly path.
This gives an error each time, when they closes a dialog, that has TFormSize on it.
If TFormSize had a propery like IgnoreErrorOnFailSave (or something like that), we would really appreciate it.
In your code, just try-except it, and catch the error there.
We added a try/except and will forward this error to a new OnError event so you can decide how to handle it. The next update will have this improvement.
